32.8 Internal Voltage Reference Specifications

Table 32-10. Internal Voltage Reference DC Electrical Specifications
DC CHARACTERISTICS			Standard Operating Conditions: VDDIO = AVDD = VDD 2.7V to 3.63V (unless otherwise stated) Operating temperature: -40°C ≤ TA ≤ +125°C for Extended Temp
Param. No.	Symbol	Characteristics	Min.	Typ.	Max.	Units	Conditions
VR_1	IREF⁽¹⁾	Internal Voltage Reference ADC.REFCTRL.REFSEL = INT1V DAC.CTRLB.REFSEL = INT1V	0.96	1	1.02	V	Over full operating temperature range
VR_3	IREF⁽¹⁾		0.97	1	1.01	V	25 °C
VR_9a	ACIREF⁽²⁾	Internal Voltage Reference Comparator AC.COMPCTRLn.MUXNEG = band gap	1.06	1.1	1.12	V	Over full operating temperature range
VR_9b	ACIREF⁽²⁾	Internal Voltage Reference Comparator AC.COMPCTRLn.MUXNEG = band gap	1.07	1.1	1.12	V	25 °C
Note: ADC and DAC reference voltages < 2.4V (i.e., < 500 µV/step) is not practical and peripheral performance is not guaranteed. See parameter CMP_23 for Comparator Reference voltage range information.
